Brainy Biology Memes For Those Who Love A Little Dose Of Science Daily (67 Posts)

Science is extremely fun to learn about, and among mammals, sloth biology is the most fascinating. According to FactRetriever, this animal can take up to 2 weeks to digest a single meal, which is the slowest time among pretty much all mammals. Sometimes they can take almost 30 days to metabolize one leaf.

The reason why their metabolism is so slow is that they are designed to live among the treetops and rarely come down, which is only when they want to go to the bathroom. They are generally safer high up in the foliage, so they only slowly make their descent when they have to evacuate their bowels. Sloths also don’t eat much; they may consume around 2.5 ounces of dry leaves a day.

There’s a lot of fascinating information to learn about birds, animals, and the creatures of the world, but the oddest and most interesting are sea cucumbers. Even though they might just seem like a sedentary vegetable, this marine animal can escape from predators by ejecting its internal organs.

Although that sounds extremely brutal, it’s a simple biological process: the creature makes its body swell like a balloon, rupturing its tissue and essentially “vomiting” its skeleton, which becomes a sticky trap for a predator. Luckily, the sea cucumber can regenerate fast and regrow its complex internal systems in just 17 days.

Most of us might jump if we even think there’s a snake nearby, but what if I told you that some of these reptiles can actually sense their prey even in pitch dark. Certain snakes, like pit vipers, boa constrictors, and pythons, can convert an organism's body heat into electrical signals that guide them to the right target in the dark.

Not all of these reptiles have this ability, but those with a pit organ can use it as a kind of antenna that detects infrared radiation from creatures warmer than the surrounding atmosphere. This organ functions like a pyroelectric material and underpins their incredible abilities.

Beyond animals, humans also have so much going on under the surface that the biological facts about our bodies are almost endless. One interesting fact is that our tongues are apparently the fastest-healing organs. This happens because of their rich blood supply and the proteins in saliva.

Tongues do so much for us, like keeping our teeth clean, helping us speak, and also tasting. This muscular organ makes so much possible, but despite its strength, it’s also very delicate. That’s why it’s important to take care of it and not let it get burnt from very hot food, like we sometimes do.

There’s something crazy the human body does after we die that nobody would ever imagine. This is when the decomposing flesh undergoes a chemical reaction that turns fat into adipocere, which feels like a semi-hard cheese and has a soap-like texture. Although this doesn’t happen to everyone, the ones who do get saponified probably never expected to be so “clean.”

One woman earned the title of the “Soap Lady” because of this, and her 140-year-old body is displayed at the Mütter Museum in Pennsylvania. People who have this condition tend to have skeletons covered with tan or grayish-white deposits that are almost waxy. Although it can certainly be off-putting to think of this happening to a deceased person, it serves as a great source of research for anthropologists.

Humans aren’t the only biologically fascinating creatures; although trees seem pretty quiet, a lot goes on under the surface. One of the biggest examples is how their underground network of roots and fungi helps them exchange information and even nutrients to support one another.

We might not be able to see all these chats with our eyes, but this respectful, symbiotic relationship between trees and microorganisms is wonderful to imagine. These beautiful plants also talk to each other through the air, holding back their branches so they don’t encroach on the other or compete for light. 

All the sciences work together to help us make sense of the world and keep progressing. One of the best examples was when French physician Jean-Baptiste Denys performed a human blood transfusion and a xenotransfusion between a boy and a sheep in 1667.

They did this because early scientists believed the lamb's purity could be transmitted to people through blood. Since Jean-Baptiste already had a 15-year-old subject who needed a transfusion, he used a small amount of sheep’s blood, which ultimately did not help much. Although his efforts were unsuccessful, over the years, this experimentation and study shone light on different methods of blood transfusion.

There’s so much happening in our bodies that it can be difficult to truly understand how everything works and comes together. One such bizarre experience is how tickling can actually trigger a panic or fear response in a person. This happens because tickling stimulates the hypothalamus, which sits above the brain stem and controls emotions and a person’s reaction to danger.

So even when a person is getting tickled, their brain might see it as an external threat and instantly put its guard up. Even though there technically might not be any danger, this automatic chemical response might be why some folks start crying or getting mad when they’re tickled for too long.

Science doesn’t have to be learned through textbooks; these memes prove there are more fun ways to learn new concepts in a more practical and interesting way. Hopefully, you took back a lot of knowledge from this list, and felt a little more intellectual while scrolling.

We’d love to hear if you got any science or biology jokes that we’ve never heard of before. All facts and memes are welcome!
